Nolan Arenado is a key figure in the Cardinals' transition as the team considers exploring trade options for him. With a full no-trade clause and a contract that runs through 2027, dealing Arenado presents challenges. Despite showing signs of decline at the plate, he remains a standout defender. The Cardinals are expected to approach him for approval on any potential trade, as moving him would not only clear space for younger players but also allow Nolan Gorman to shift back to his natural position at third base, enhancing his development as a hitter. The team may need to include cash in any deal to secure noteworthy young talent in return.
